For those wanting to add page numbers to existing PDFs, Smile has released new versions of PDFpen and PDFpenPro, their PDF manipulation software. Version 5.5 adds the capability to put page numbers in either the header or the footer of the page, and the page numbers can start on any page. Visually, page numbers can be aligned left, right, or center, or even inside or outside for facing pages, and they can be formatted as Roman numerals, letters, or Bates Numbering. Also new in this update is initial support for full-screen mode in Mac OS X 10.7 Lion, along with some unspecified bug fixes. ($59.95/$99.95 new, free update, 41.5 MB)
Customize Open/Save Dialog Sidebars
You can customize the sidebar in an Open/Save dialog the same way you can in a Finder window: you can reorder the position of items, drag them off into puff-of-smoke oblivion, and even drag a folder from the dialog's list into the sidebar.
